Reissued Dec. 23, 1930 PAT ENT OFFICE OTTO 11/1. REXINGER, 011 BEVERLY HILLS, CALIFORNIA WINDOW GRATING- Original No. 1,662,167, dated March 13, 1928, Serial No.157,565, filed December 28, 19516. Application for reissue filed May 12,

In this specification, and the accompanying drawing, I shall describe and show a pre' ferred form of my invention, and specially mention certain of its more important objects. I do not limit myself to the forms disclosed, since various changes and adaptations may be made therein without departing from the essence of my invention as hereinafter claimed; and objects and advantages, other than those specifically mentioned are included within its scope.

My invention relates to removable gratings for the protection of window openings and the like. Among its principal objects are;

1 first, to provide an expansible grating that may readily be inserted between the jambs of a window casing beneath or above a raised or lowered sash; second, to furnish facilities for locking the grating in position to prevent its removal by unauthorized persons; third, to afford ready means for attaching canvas or other roller curtains on either or both sides of the grating at will; and, fourth, to supply a relatively simple and inexpensive device adapted to function in the ways just stated.

My objects are attained in the manner illustrated in the accompanying drawing, in which Figure 1 is an elevation of a window opening with a portion of the window frame at the left partially broken. away, and with my improved grating installed there-in beneath a sash; and

Figure 2 is a horizontal section of the casing of the above window, taken on the line 22 of Figure 1, and with my device shown in plan in operative relation thereto.

Similar reference numerals refer to similar parts throughout the views.

My grating comprises a pair of variably spaced upright side members 5 spanned by a series of spaced telescoping bars. The latter consist of outer tubes 6, and inner bars 7 Within each of the outer tubes is a helical compression spring, as shown at 8. These 1930. Serial No. 451,771. 1 I r springs press against the inner ends of bars 7 and tend to expel them from tubes 6, and thus force side members 5 apart. A cross bar 9 spans two of the tubes 6, and a similar cross bar 10 spans the corresponding pair of bars 7. These cross bars serve as grab-holds whereby the side members of the grating may be brought nearer to each other when the grating is to be installed or removed.

In theform of my invention selected for illustration the side members 5 are made of channel iron having a width only slightly less than the thickness of the window sash, so as to be able to enter the sash runway of the wmdow frame. The edges of the channel flanges preferably are dendated as at 11, to enable them to better engage jambs 12 of the'window frame. At the tops of the side members are brackets 13 adapted for supporting shade rollers when it is so desired. These brackets and they may be placed either on the outside or inside of the grating, or on both sides as shown.

A locking mechanism of suitable type is provided at 14, whereby the grating may be locked in its extended position in the window frame to prevent it being removed by unauthorized persons.

The operation of my invention will be clearly apparent from the foregoing description when. it is further stated that, to efitectively protecta window opening thereby, all that is necessary is to raise the sash 15 and put my grating below itinthe sash run ways lock-ingit in its extended position;

' Having thus fully described my invention I claim:

' 1. A device of the" character described, comprising a pair of'va'riably spaced parallel side members; a plurality of'spaced paired telescopic members connecting and aligning the side members; springs" within, the outer telescopic members adapted for pushing the inner telescopic members outwardly tdseparate the side members; and means for locking the telescopic members in extended position.

2. In combination, a pair of oppositely arranged grating sections, each section being composed of a rigid side member and a series of angularly-disposed spaced apart rails, means whereby the railsot' one section are guided rectilinearly of the rails of the other section slidably, resilient means opposing the sliding of the rails of one section relatively to the rails of the other section, and means interposed between adjacent rails of both.

-3. A device of the kind described consistby both grating sect-ionsadapted to be anchored against window jambs of a window structure when the grating sections have been extended adjustably their greatest distances apart across the width of the window opening, resilient means holding the rails of both sections in extended relation, and looking means for locking the adjustable rails of both sections internally to prevent contracting the distance between the anchored means of both rails.
